Comparison of Sodium Hypochlorite Made with Typical Production Process
Versus High Efficiency Production Process
As costs for chlorine and caustic continue to rise, many sodium hypochlorite producers are looking at equipment and process efficiencies that can pay big dividends in raw material savings. For example, simply lowering excess caustic to the 3gpl to 4gpl range, optimizing sodium hypochlorite strength, and maintaining sodium chlorate levels in the 1gpl range, could save hundreds of thousands of pounds of raw materials annually - and hundreds of thousands of dollars in raw materials costs, as well.
To find out how much you can save by implementing process and equipment enhancements that result in better process control, lower recycle temperatures, and improved repeatability, input the appropriate values into the interactive tool below.
1. Input values into the orange input boxes located on the left hand portion of the interactive tool.
Note: Typical Production Process input values to correspond with values of the sodium hypochlorite you typically produce.
High Efficiency Production Process input values to correspond with the values of the sodium hypochlorite you would like to produce.
2. Select the "Weight Percent of Caustic for Dilution at 600 F (32% or 50%).
3. Select the purchase price of caustic, the purchase price of chlorine, and the gallons of sodium hypochlorite sold per year by moving the mouse arrow over the appropriate dial. Then, while holding the left mouse button down, move the mouse up to increase the value or down to decrease the value.
Interpreting the Results
The bar at the lower left side of the screen will illustrate the annual raw material savings in US dollars you could achieve with a high efficiency production process.
Powell will be pleased to answer any questions concerning this interactive tool and the reasons for the significant differences in efficiencies when comparing typical production processes to high efficiency production processes.
*In order to illustrate savings possible with production efficiencies, it is important to use accurate pricing for the raw materials. Incorrectly entering the values of the chlorine and caustic will significantly skew the savings possible with the use of improved systems. if the chlorine plant is at 100% capacity and all the production is sold, then the price of chlorine and caustic is the selling price. If the plant has excess capacity, then the chlorine and caustic price is the variable cost of the products.
